How often does the American Medical Association (AMA) update the CPT code set?

The American Medical Association (AMA) updates the Current Procedural Terminology (CPT) code set annually. This annual update process typically occurs in January, allowing healthcare providers and coding professionals to stay current with changes and additions to medical procedure codes that reflect advances in medical practice and technology. This ensures that the CPT code set accurately represents the services rendered in healthcare settings. The annual cycle allows comprehensive revisions to be made, capturing a wide array of changes more efficiently than more frequent updates would.

The other options reflect more frequent update schedules that do not align with the AMA's established practice, as updates are not performed monthly, quarterly, or biannually. This structure balances the dynamic nature of medical practice with the need for stability in coding standards.
